A wide range of jobs exists in the dairy industry to fulfill a variety of needs. There are dairy jobs on farms, where your duties involve helping with the birth of calves, administering vaccines to cows, and operating the machinery that milks cows and purifies the stored milk. As a livestock veterinarian, the health and welfare of the cows and calves on dairy farms are your responsibilities. Alternatively, you could work as a food scientist creating products derived from milk or cheese. Some job listings for dairy jobs refer to retail associates in the dairy department of grocery stores.
